Just‐in‐time for supply chains in turbulent times
针对新冠疫情等 disruptions 引发的准时制（JIT）与备货制（just-in-case）之争，本文澄清了关于 JIT 的常见误解，并提出了在动荡环境中调整 JIT 的方法，指出恰当选择 JIT 供应链环节可提升绩效，尤其在 disruptions 期间。
The Covid‐19 pandemic and other recent disruptions in the early 2020s led to sections in the business press blaming just‐in‐time (JIT) practices for operational failings. Consequently, there are calls for moving away from JIT toward holding more inventory as preparation against future disruptions, which is referred to as just‐in‐case. The academic community is also divided. Some scholars argue that JIT is not resilient, while others maintain that JIT can continue providing superior performance even with disruptions. Motivated by this debate, we discuss various misconceptions about JIT that underlie this debate. Furthermore, we present different ways to adapt JIT for turbulent environments and argue that companies can improve their supply chain performance if JIT supply chain segments are chosen fittingly—even more so—during disruptions.
